Sonogenetic Control of Engineered Probiotics for the Treatment of MASH by Modulating the Gut‐Liver Axis

open access: yesAdvanced Science, EarlyView.
Researchers developed an engineered probiotic encapsulated in an inulin hydrogel, enabling ultrasound‐triggered intestinal delivery of IL‐22. In MASH model mice, this system remodeled gut microbiota, strengthened the intestinal barrier and reduced portal LPS and hepatic IL‐6.

Oral Actinomyces Species Exposure is Associated with Anxiety‐Like Behavior, Mitochondrial Remodeling, and Altered GABAergic Pathways

open access: yesAdvanced Science, EarlyView.
Oral exposure to cannabis‐associated Actinomyces species, particularly A. meyeri, is associated with anxiety‐like behavior in mice in the absence of detectable bacterial translocation or overt systemic inflammation. These findings support a potential oral‐brain metabolic axis involving candidate metabolites such as arginine and argininosuccinate ...

Production of urea but absence of urea cycle in pancreatic islet cells

open access: yes, 1988
Rat pancreatic islets produce large amounts of urea when exposed to L-arginine (10 mM). However, no urea cycle seems to be operative in islet cells.

Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

open access: yesAdvanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

Dual‐Dynamically Crosslinked Nanogels Enable Prolonged Ocular Retention for Multimodal Dry Eye Therapy

open access: yesAdvanced Science, EarlyView.
This berberine‐loaded dual‐dynamically crosslinked nanogel integrates tannic acid‐zinc metal‐phenolic networks and carboxymethyl chitosan/aldehyde‐functionalized poly(ethylene glycol) dynamic Schiff base networks, achieving 1‐year colloidal and antioxidant stability, sustained corneal berberine exposure for 24 h to support convenient once‐daily dosing,

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

open access: yesAdvanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...

Order-Disorder Transition in Urea-Polyethylene Complex

open access: yes
The phase transition of urea complexes whose guest components range from n-paraffin to polyethylene was investigated by DSC thermal analysis. The transition temperatures increased with increasing the chain length; the related heats did not change much ...
